Application filed October 30, 1905 Serial No. 285,007.

- -The object of my invention is to provide a chock for holding-.logs oncars, trucks, andother means for-transportation, which chock may bereadily released to enable the logs to be rolled from the car Withoutthe necessity of a .person going to the side of the ear from which thelogs are to be rolled.

It is also an object of my invention to improve the means for mountingthe chock and to enable the chock to be. thrown into unloading orinactive position so completely as not to interfere in any way with thefree rolling of the logs,

The invention involves various features all of-which will be fullybrought out hereinafter I and particularly pointed out inthe claims.

' logs rest.

' Reference is to be had to the accompanying drawings, whichillustrate'the preferred embodiment of my invention, and in which-Figure l is a plan view of thelat-car having my invention applied. Fig.l2 is an enlarged cross -section showing the guide rails for mountingthe chocks and on which rails the Fig. 3 is a detail section showing oneof the checks in unloading position, and Fig. 4. is a detail perspectiveof the stationary chock.

The invention is adapted to be used on flatcars, trucks, and on variousother means for transportation on which logs and timbers may be loaded.As here shown, .it is illustrated applied to anat-carl@ Near each end ofthe` car is located a` pair. of railroadrails 11. These rails 'extendparallel with each other transversely ofthe car and may be mounteddirectly on the floor of the car or 0n a bunk or pillow provided forthat purpose, As shown\best in Fig. 2, the rails A11 are 'laid sidewiseon the support and are drawn down In' so firmly in place by means ofbolts 12.

v drawing down .the rails the, 'comparatively sharpged'ges of thebase-flanges cut into the support', whether it be the -floor of thefiatv'car ora bunk provided to carry the rails, thus making. thev railsabsolutely rigid and' secure.

Said rails are arranged with the balls of the rails inward, and theballs are slightlyspaced apart to provide a channel for a chain 14, thepurpose of which chain will be fully set forth hereinafter. Thebase-flanges of the rails are outward and project above the balls. Theballs of the rails form a trackway on which the checks are movablycarried, and the baseiiang'es of the rails, which project upward, y

(see Fig. 2,) serve the double function of sustaining the logs and offorming guard-flanges preventing the displacement of the checkslaterally of the rails. The relatively sharp edges of thebase-flangessink'into the logs, so as to prevent the car from beingpulled out from under the log. This is especially useful when theinvention is employedin connection with trucks, since in this case it isusual to carry `a group .of logs on two4 trucks which are connected onlyby the logs themselves. Two chocks are employed for each pair of rails,one chock at each end thereof. These checks are designated 15 and 16,respectively.

The ehocks 15-are adjustably carried on the balls `of the rails betweenthe base-flanges. y

Any desired means may be employed for adjustably holding said chock. A

As shown in Figs. l and 4, the checks arev provided with pins 17, whichenter openings 18, formed in the webs of the rails 11. The movablechocksl are free to slide on the walls of therails between thebase-flanges, and

with the movable chock 16 the chains 14 are connected'. l Both of theebooks 15 and 16 are of the angular form'best, illustrated in Figs.' 3and 4, and the checks 16 are arranged with an essentially right-angularform, so that when moved to the ends of'th'e rails 11 the checks maybe'thrown down into the folded position, (shown in Fig in which v vInthis position the chock lies below the upper edges' of the `rails 1 1and entirely out of the wa y oflthelogs rollingfr'o'm the sani'e.n AtAthe ends ofthelrails i adjacent' lto the adjust- 1 able checksl `1ffeyesvv19 are provided, qthrough f which the chains le pass.l Coacting with'Ak :said eyes are claws 20, which are preferably 1 loo,

the claws. These claws are adapted removably to engage the chains le andthe eyes 19, so as to prevent the chains from being moved *y through theleyes in such direction as will per-- ymit thedumping-chock's to reachthe edge of the car and accidentally assume the inactive I'or unloadingpositionabove described In' the use of the invention` the logs are'loaded on the car and extend edfroni one pair of rails 11 to the other,the checks 15 and 16 being placed imposition so as to retain the logs inthe fdesired arrangement.` The stationary chock's lvare held by the pins17 and the movable checks 16 are held by the chains 14, eyes 19, andclaws 20. When it is desired to unload the logs from the car or otherconveyance on which the logs are laced, the claws 20 should bedisconnected om the chainsla and the pressure of the logs allowed toslide nthe movable chock 16 out to the edge'of the car or the adjacentends of the rails l l, whcreuponthe chocks will Jall down into theunloading position (shown in Fig. 3) and allow the unobstructed movementof the logs. It will be observed that this operation is performed bypersons standing at the side of the car having the 'eyes.19 and claws20, it being only necessary to disengag'e the claws from the chains 14and to start the logs rolling toward the opposite side of the car. Thisavoidsthe extremely .dangerous operationi of a person going to the sideof the car op which the logs ,are unloaded for the purpose of releasingthe chock. ln the lumbering industry numerous fatal accidents occur'fromthis reason. 4 l

It is pointed outthat while it is preferable to employ railroad irons orrails, as used in theA drawings and hereinbefore described, guide-railsof other forms may be employed, in which, connection it is onlyessential that means be provided for forming a central paschainis-rove,` and `'apela-vv grappling-hook sagev for the chain, a surfaceon which the checks maybe slidably supported, and guardsurfaces at thesides ot the checks to prevent them from moving laterallylfroin therails.

Various changes in the form, proportions, and lminor details of myinvention may be re sorted to at will without de arting from the spiritand lscope thereof` llience l 'consider myself entitled to all suchvariations asmay lie within the terms of my claims.v -A
